super six parts?

I read somewhere that tha cam used on the 1978 slant was the one to use if converting an older slant to a super six. Do you know if this is true? I'm thinking of building up my 170 a bit and running a 2 bbl on it with a real 4 speed behind it, not one of those overdrive things they used in the aspens & volares but one from a 65 cuda. I'm wondering if this cam & carb arangement will help it any . I really want the 170 for the gas milage but a bit more power would be a good thing too.
